This app is heavily expensive. Each small feedback costs credits. There is no premium version, you have to purchase credits over and over again in order to maintain proper feedback. Without credits you even don't get the information if my answer was right or wrong. Ridiculous! Besides there are a huge amount of bugs as well.

I just wanted to pop out here and say that I've read lots of criticism before downloading the app but still decided to give it a go and I ain't regretting ma decision one bit. Cuz it's a masterpiece for a brokie like me who got no money to pay for the practicing websites. Got tips and exercises as the real exam I see no difference with the websites so just give it a try and thank me later. Appreciate u the creator!

Letters are incomplete in the app. All the way. Example: fantastic is written as fantasti. Can't guess if it's error or correct word. If you press word is wrong you answer is wrong. Not sure which language it is.
